No. The way data is organised in memory is dramatically different in
Haskell when compared with C. You need to write functions to read in
each field in turn and then "reconstruct" the structure on the Haskell
side.
It's a tedious process. My advice is that if you have a lot of
structures to read, write a (simple) preprocessor to generate the
marshalling code.. that's what I did.
